Referring to the drawings thenumeral Iii indicates the casing or support, 16 lar extension or barrel thereof, and 17 the terminal insulating plate which forms the rear cover for the casin The casing is of cup like shape .with its bottom portion forming the front'end of the casing and on which end'a'dial plate 18 is rigidly mounted. The center portion of the casing is provided with an opening 19 to receive the inner open end of the extension 01' barrel 20 which is also rigidly connected thereto. The extension barrel 20 is formed of comparatively thin metal and is providedwith elongated peripheral loeking slots 21 and an outer end opening 22 of less of the extensionto form an annular shoulder 24. The locking slots 21, of which there are preferably two, are spaced'equi-distant circumferentially from each other and are 0 a width corresponding to, the width of the transversely extending tumbler slot 25 of the lock cylinder 26 which is revolubly mounted in the extension barrel 20. The lock cylinder 26 is formed with a reduced forward end portion 27 which projects through the reduced outer'end opening 22 ot' the extension barrel, and the shoulder 28 formed by said reduced portion abuts against theshoulder 24 of the barrel and properly positions the two arts with relation to each other. A It y slot 29 of irregular shape transversely nally through the central 4 cylinder and intersects the ansversc tumbler slot 25. A key 30 having-""ijts'two opposite edges 31 of reverse irregular shape not the lock and its width approximately "the; same. throughout its tumbler engaging portions is shaped or corrugated transversely to fit.

is adapted to extend":

the key slot and through the elongated openings 25). of the flat tumblers 1}? reciprocally mounted inthe lock cylinder slot when said hey is inserted in the. key slot. The. llat tumblers extend transversely in and closely lit the cylinder slot and are all. of a length correspomling lo the diameter of the loclg cylinder so that when their outer end edge portions are alined and flush with tho periphery of the lock cylinder, the cylinder may be freely turned within the extension barrel of the easing-by the key. \Vhile all of the elongated medial openings 32 of the tumblers are of the same length they vary in distances from the opposite ends ol? the tumblers aml form an irregular opening or slot which in shape conforn'is approximately to the edge -onlour of the. portion of the key engaged by the tumblers when said tumblers are in aliucd unlocked position as indicated in Fig. 2.

The lighting contact ring guide 41 is pro:

-vided with opposite outwardty projecting guide fingers 45 which extend into the pe ripheral guide recesses 4-6 of the floating lighting contact ring member -17 and guide said member axially while turning from one position to another. Said guide lingers 45 are not directl t diametrically opposite each other but are offset a few degrees and the guide recesses of the guide brine; member 47 are also correspom'lingly offset to make it inn'mssible to i1u .-orrectly position the ring The ring guide is also provided with three outwardly extending: guide pins -18 for receivingcoilml-sprine's 49 which surround the pins and are interposedbetween the lighting contact. rin5 guide et-l and'the lighting contact ring member 47. The; outer cnds of the springs and the guide pins extend into recesses or sockets 5O tormed'in the ring member -11.

It will be noted that the rim: member t? is made in two parts, complementary sheets of'dielectritmaterial in face contact. The sockets. 50 are constructed by punching holes completelythrough one of the sheetsot dielectric mm terial above referred to, and owning the other sheet of such material to present an impertorate portion to each such hole, Thereby the sockets are economically constructed with accuracy to the desired depthprefer the construction illustrated be cause of-the fact that the ring member 1.? may be more economically manufactored in the manner described than would be possihie if it were attempted to bore the sockets 50 to the desired depth in av singlesheet of dielectric material.

The lighting contact. ring: member at? is formed of insulating'material and on its outer face is mounted'a metal contact ring- 51 having three outwardly embossed rounded or hemispherical contact portions 51 which are adapted to engage the rounded end recesses'of fixed lighting contacttcrminals 52,. 53, 54, and' 55 mounted in the terminal in sulating plate 17. The springs 49 pressing on the contact ring at three points approxispaced, permits the contact ring to float or more in any dircw portions 51 to automatically center, in. the terminal recesses and form a positive electrical contact with the terminals as well asto-iindica-te with a and comprises two- 47 are likewise. otlset to pref the ends of the spring (it) and hold the spring positive snap of the ring. line and between the contact terminals, the terminal plate 17 is provided with three rounded recesses 56 to receive the rounde contact portions 51' when the lighting contact ring is in off position. The lighting terminals are adapted to be connected to a one-wire lighting circuit in the manner shown in Fig. 12 or in an Y other lighting circuit combination desirec. In said. Fig. 12 the head lamps are indicated by 57, the dim lamps by 58, and the tail lamp by 59. In said circuit a generator 60 and a battery 61 supply the current. An ignition-coil 62, a circuit breaker 63, a spark plug 65 are also diagrammatically indicated.

Said pin portions are of dillercnt diameter from each 3 other and the diameters ol the openings (38 also vary to correspond to prevent incorrect positioning of the switch member on the pin portions. A coiled spring 69 interposed between the lock cylinder and the ignition switch member and between the pin portions 67 holds the switch member yieldingly in position. Both the lock-cylinder and the ignition switch member are provided with central recesses 70 and 71 to receive in position.

The ignition switch member is also formed.

of insulating material and onits outer face is mounted a metal contact. ring T2 having three. outwardly projecting ro'unded or hemispherical contitrl. portions 721' which are adapted to engage the rounder cudv recesses of fixed ignition" contact terminals 73, 74, 75, and T6; .Said ignition contact terminals are concentrically mounted in the terminal insulating plate 17 \itllllhtllti circle of lighting terminals. The terminalpla-tc is also provided with three position recessed portions 77 to receive the rounded ignition contact portions 72 portions are in oil position. While in Fig.
